Welcome L&T Special Steels & Heavy Forgings to NucFinder
L&T Special Steels & Heavy Forgings is now available on NucFinder as a validated supplier.
L&T Special Steels and Heavy Forgings Private Limited (LTSSHF) is a strategic joint venture between Larsen & Toubro (L&T) and Nuclear Power Corporation of India Limited (NPCIL). Located within the A. M. Naik Heavy Engineering Complex in Hazira (Surat, Gujarat), LTSSHF operates India’s largest integrated steel-making, heavy forging, heat treatment, and heavy machining facility. Spanning over 400,000 square meters, the plant was established to supply high-reliability forgings for critical, high-technology sectors.
Focus on Nuclear Energy & Strategic Sectors
LTSSHF holds a distinct position as the only facility in Southeast Asia capable of manufacturing nuclear-grade heavy forgings. Its creation significantly strengthened domestic self-reliance while providing global access to nuclear-grade components.
Key Nuclear Capabilities & Milestones:
- Reactor Component Forgings: Manufacturing heavy, high-purity forgings for 700 MWe Pressurised Heavy Water Reactors (PHWR) and Light Water Reactors (LWR), including reactor pressure vessels, steam generator tube sheets, pressurizer shells, and main coolant pump housings.
- Nuclear-Grade Alloys: Expertise in custom melting and forging low-alloy steels (such as SA508 Gr 3 Cl 1, 20MnMoNi55), nuclear-grade stainless steel (e.g., SS 304L), and high-nickel alloys.
- International Fusion Energy (ITER): Manufactured and supplied heavy nuclear-grade stainless steel plates (thicknesses up to 900 mm) for the global ITER project in Cadarache, France.
- Spent Fuel Casks: Production of heavy forged components for spent nuclear fuel transportation and storage casks.
- Nuclear Quality Assurance: Operations adhere strictly to international nuclear compliance frameworks, including ASME Section III (N-stamp qualifications), IAEA safety codes, and ISO standards.
Core Infrastructure & Technical Capabilities
The integrated facility at Hazira enables complete, end-to-end manufacturing from raw materials to fully machined heavy components:
- Steel Melting Shop: Equipped with a 120 MT Electric Arc Furnace (EAF), Ladle Refining Furnace (LRF), Vacuum Degassing (VD), and Vacuum Oxygen Decarburization (VOD) units for low-impurity steel production.
- Ingot Casting: Facilities for both bottom-pouring and large-scale vacuum ingot casting.
- Heavy Forge Shop: Powered by a 10,000-Ton Hydraulic Open-Die Forging Press integrated with a 150 MT rail-bound manipulator, capable of shaping massive ingots into complex geometries.
- Heat Treatment Shop: State-of-the-art furnaces handling single components up to 400 MT, supported by a 1-million-litre liquid quenching system.
- Precision Machine Shop: Heavy-duty vertical turning lathes (handling loads up to 250 MT), horizontal lathes, floor-type horizontal boring machines, and deep-hole drilling equipment (up to 15 m depth).
Other Key Industry Sectors Served
In addition to nuclear power generation, LTSSHF serves several other heavy engineering markets:
- Defence & Marine: Heavy forgings for naval vessels, submarines, and strategic defence platforms.
- Hydrocarbon & Refining: Heavy-wall forged shells and heads for high-pressure hydrocracker reactors, process columns, and coke drums.
- Power Generation (Thermal & Hydro): High-integrity forged turbine rotors, generator shafts, and hydro-runner hubs.
- Heavy Equipment: Specialized forged components for steel manufacturing mills, heavy presses, and offshore engineering installations.
